Question

我如何在新的一线服务。我研究了其他问题,但为我干.。在我服务时,我需要做什么变化?

Answer 1

重新命名:Start(final) 意向书,最后定本启动书(Id) 至_onStart,并使用新的<条码>执行:

 @Override
 public void onStart(final Intent intent, final int startId) {
     Thread t = new Thread("MyService(" + startId + ")") {
         @Override
         public void run() {
             _onStart(intent, startId);
             stopSelf();
         }
     };
     t.start();
 }

 private void _onStart(final Intent intent, final int startId) {
     //Your Start-Code for the service
 }

<>Ampent5和

public void onStart (Intent, int) was depreced at55/2。本条应改为:StartCommand(Intent, int)

@Override
public int onStartCommand(final Intent intent, final int startId){
    //All code from  onStart()  in above placed here as normal.
}

private void _onStart(final Intent intent, final int startId) {
     //Your Start-Code for the service
}

我不认为你可以在新的一线上开始服务,但你可以做的是,在你的工作上,你可以做些什么。

This is because like the activity, the service has life cycle methods that run on the main thread.

So your service will run on the main thread but it will do the heavy lifting on a new thread that it creates when ever it needs to.

我希望它能够提供帮助。

引用rel=“nofollow”http://developer.android.com/vis/android/app/service.html

"Note that services, like other application objects, run in the main thread of their hosting process. This means that, if your service is going to do any CPU intensive (such as MP3 playback) or blocking (such as networking) operations, it should spawn its own thread in which to do that work. More information on this can be found in Processes and Threads. The IntentService class is available as a standard implementation of Service that has its own thread where it schedules its work to be done."

In my project, i have someone like this and it s work:

Thread welcomeThread = new Thread() {
@Override
public void run() {
    try {
        super.run();
        while (isMyServiceRunning() != true) {
            sleep(100);
        }
    } catch (Exception e) {
        System.out.println("EXc=" + e);
    } finally {
        Intent i = new Intent(getApplicationContext(), MainPage.class);
        i.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
        startActivity(i);
    }
}
};

welcomeThread.start();
